into the flame. After 12 seconds of flame application, the burner shall be removed from below

the specimen and immediately turned off. The burn length and the time of burning after

removal of the flame shall be recorded. The burn length shall be the distance from the original

bend made in the conductor to the farthest point of damage. Damage shall consist of bare

conductor and charred insulation. Light discoloration of the insulation shall not constitute

failure.

4.6.8 Immersion

Specimens of sufficient length to perform the subsequent tests shall be measured at their

midpoints to determine their initial diameters, and shall then be immersed to within 6 inches

(152 mm) of their ends in each of the fluids (using a separate specimen for each fluid) for the

time and temperature specified in Table 4. During immersion, the radius of bend of the

specimens shall be not less than 14, nor more than 35, times the specified maximum diameter

of the wire or cable under test. Upon removal from the fluids, the specimens shall remain for 1

hour in free air at room temperature. The diameters shall then be remeasured at the original

point of measurement and compared to the initial diameters. The percent change in diameter

shall then be calculated. For finished wire, 1 inch (25 mm) of insulation shall be removed from

each end of a 24-inch (610-mm) length of each specimen. For finished cable, 2 inches (51 mm)

of the jacket shall be removed from each end of a 24-inch (610-mm) length of each specimen,

and the shield shall be pushed back and formed into a pigtail at each end of the specimen. One

inch (25 mm) of insulation of each of the primary wires shall then be removed from each end

of the specimen. The specimens shall then be subjected to the bend test (4.6.1 - use the

mandrels and test weights specified on the applicable specification sheet for the Crosslinking

Proof Test), followed by the voltage withstand test (4.6.14).

4.6.9 Insulation Elongation and Tensile Strength

Specimens of the entire insulation shall be carefully removed from the conductor and tested for

tensile strength and elongation in accordance with FED-STD-228, Methods 3021 and 3031,

respectively, using 1-inch (25-mm) bench marks, a 1-inch (25-mm) initial jaw separation, and a

jaw separation speed of 2 inches (51 mm) per minute. For cables, the method shall be the same,

but only the cable jacket shall be tested.

4.6.10 Jacket Concentricity

The concentricity of the cable jacket shall be determined by first locating and recording the

minimum wall thickness measured on a cross-section of the jacket. The maximum wall thick-

ness of this same cross-section of the jacket shall also be measured and recorded. The ratio of

the minimum wall thickness to the maximum wall thickness shall define the concentricity. All

wall-thickness measurements shall be made under suitable magnification. The wall thickness

shall be the radial distance between the inner and outer rim of the jacket.

4.6.11 Jacket Flaws

Finished cable shall be tested in accordance with the jacket flaws test of MIL-C-27500, or

the impulse dielectric test procedure of MIL-W-22759, with the shield grounded at one or

both ends.

4.6.12 Life Cycle

Finished wire and cable specimens, prepared in accordance with 4.6.12.1 or 4.6.12.2, as

applicable, shall be conditioned in an air-circulating oven for 500 hours at the temperature

specified. The velocity of air past the specimens (measured at room temperature) shall be

between 100 and 200 feet (30 and 61 m) per minute. After conditioning, the oven shall be shut

off, the door opened, and the specimens allowed to cool in the oven for at least 1 hour. When

cool, the finished wire specimens shall be freed from tension, removed from the mandrel, and

straightened. The finished wire and cable specimens shall then be subjected to the bend test

(4.6.1) followed by the voltage withstand test (4.6.14).

4.6.12.1 Finished Wire Preparation

One inch (25 mm) of insulation shall be removed from each end of a 24-inch (610-mm) speci-

men of finished wire. The central portion of the specimen shall then be bent at least halfway

around a horizontally positioned smooth stainless steel mandrel of the diameter specified in the

applicable specification sheet for the Crosslinking Proof Test. To prevent sticking of the speci-

men to the mandrel, the mandrel shall be covered with polytetrafluoroethylene in the form of

either a dispersion coating (preferred) or wrapped tape, provided that the diameter of the

mandrel still conforms to the applicable specification sheet. Each end of the conductor shall be

loaded with the weight specified in the applicable specification sheet for the Crosslinking

Proof Test, so that the portion of the insulation between the conductor and mandrel is under

compres-sion while the conductor is under tension. This specimen, so prepared on the mandrel,

shall be conditioned and tested as specified above.

4.6.12.2 Finished Cable Preparation

Two inches (51 mm) of the jacket shall be removed from each end of a 15-inch (380-mm)

specimen of finished cable, and the shield, if any, shall be pushed back and formed into a

pigtail at each end of the specimen. One inch (25 mm) of insulation of each of the primary

wires shall then be removed from each end of the specimen. The cable specimen shall then be

loaded with sufficient weight to hang straight, and shall be conditioned and tested as specified

above.

4.6.13 Secant Modulus

Specimens of the wire insulation, or cable jacket, shall be carefully removed and tested for

secant modulus in accordance with ASTM D 882, using a 2-inch (50-mm) initial jaw separa-

tion, a jaw speed of 0.2 inch (5 mm) per minute, and a chart speed of 20 inches (508 mm) per

minute. The pounds-force (N) shall be read from the chart 4 inches (102 mm) from where the

trace begins to rise for 0 pounds-force (N).

Secant Modulus (lbsf/in2 @ 2%) =

4.6.14 Voltage Withstand

The uninsulated ends of the specimen shall be attached to an electric lead. The specimen shall

be immersed in a 5-percent, by weight, solution of sodium chloride in water at 20 to 25°C,

except that the uninsulated ends and 1.5 inches (38 mm) of insulated wire or cable at each end

of the specimen shall protrude above the surface of the solution. After immersion for 5 hours,

the voltage specified in the applicable specification sheet shall be applied at 60 Hz between the

conductor or the shield, as applicable, and an electrode in contact with the liquid. The voltage

shall be gradually increased at a uniform rate from zero to the specified voltage in 0.5 minute,

maintained at that voltage for a period of 5 minutes for finished wire specimens and 1 minute

for finished cable specimens, and then gradually reduced to zero in 0.5 minute.

4.6.15 Weight

The weight of each lot of finished cable shall be determined in accordance with the procedure

specified for finished wire in MIL-W-22759.
